Post Turbo 350 wide open throttle shift adjustments

I'm running a turbo 350 behind a 468 with a B&M 3000 Holeshot and 3.73 gears, 284 magnum,performer rpm,750 holley. If left in Drive it shifts around 4400 rpm at wide open throttle, it just plain rolled over and died at the drags 13.95@90mph. How can I adjust this tranny to shift around 5500- 6000. I've heard talk about a the vacuum modulator, so I replaced that and no luck Could it be the governor ? Where's it at and how can I adjust it without spending a fortune. PS. Have had both knees replaced so gettting up and down on the garage floor ain't as easy as it used to be. Thanks, any help would be appreciated.

Hi
I have the opposite problem. I have a 350ci stock ChevyVan with a TH350. I have installed a single turbo set-up. The maximum RPM of the engine is 4000RPM. So I want the transmission to shift at 4200RPM. Now it would shift at 5000, 5500? I installed a vacuum modulator. I adjusted the modulator and kick down cable and now it shift firm at 4500 RPM with a boost pressure of 6 psi. When I rise the boost pressure to 7 psi, shift point rise to.
Maybe you can do something with this? Pressure on the modulator or something.

The governor is important for the WOT shift points. It's possible to buy recalibration kits. I think B&M makes one. It's just a bunch of weights and springs. The governor is really easy to get to. On the driver side of the tranny, close to the tail, you'll see a round cover on the outside. Sometimes these are held in place with a large clip over the cover. Take the cover off and voila, your governor is right there. It'll come out really easy, and then just follow the instructions which come with the recalibration kit. Good luck,
dh

The new Chevy High Performance magazine has an article about the governor kits.
